another fix to the build system, the current way we check for lib dependencies do not handle lowercase vs. uppercase name differences correctly when using pkg-config. The only lib dependency that currently has this is Xcursor, so i removed the lowercase version so that "Xcursor" will be the only one that is searched for.
